Hi,
I recently bought a Seeed XIAO ESP32S3 Sense and I’m having trouble to get the camera to work properly.
One of the issues is that I’m being only able to take one picture and after that I get an error and it stop work until I reset the board.
I’m using a simple HTTP server implementation to get the picture on a browser.
Here is the error:
W (29749) cam_hal: Failed to get the frame on time!
** Even setting the log output verbosity to “Verbose” that is the only error message I see on terminal.
And here is my code:

I have spent days trying to solve it with no luck. Can’t find anything on Google either.
I suspect I’m missing something very basic?!
Any help is really appreciated!
TIA!
